1 Claim.

Our invention relates to'improvements in window strips for use with window sashes and the primary object thereof is to provide a. strip of this character which tensions the sash against rattling and is permanently connected to the window frame for manipulation to permit removal of the sash from said frame.

Another object is to provide a device of the character and for the purposes above set forth which functions as a weather strip, is inexpensive to manufacture, can be readily attached to the usual window frames and is strong and durable.

To the accomplishment of the above and the subordinate objects presently appearing a preferred embodiment of our invention has been illustrated in the accompanying drawing, set forth in the following description, and defined in the claim appended hereto.

In said drawing:-

Figure 1 is a view in side elevation of our improved window strip.

Figure 2 is, a view in transverse section taken through a portion of a window frame and sash and illustrating our improved window strip attached to the window frame.

Figure 3 is a fragmentary view in perspective of a female member forming part of the window strip.

Referring to the drawing by numerals, l' designates a portion of the usual window frame, 2 the lower sash, and 3 our improved window strip.

The strip 3 comprises an inner strip-like male member 4, of wood or other suitable material, having a front edge 5 telescoping in a female member 6 of U-shaped form in cross section and preferably formed of metal. The male member 4 and female member 5 as will be understood, are co-extensive in length with the inside height of the frame I as is usual and are imposed flat against the inner face of the side of said frame.

The closed end or edge of the female member 6 is hinged, at suitable points, as at 1 to the corner of the frame I for swinging movement of the composite strip out of said frame as shown in dotted lines in Figure 2 so that it is clear of the inner confines of the frame I thereby permitting removal of the sash 2. The inner edge 8 of the male member 4 is of rightangled form and designed to bear fiat against the sash 2. A longitudinally extending guidegroove 9 is provided in the edge 4 to slidably receive guide screws 9' threaded into said sash 2 whereby the latter may be elevated and lowered relative to the member 4. Interposed between the members 4 and 5, and within the latter, are compression springs Ill arranged at suitable intervals, one end of each spring seating in a socket II in the front edge of the member 4 and the other end of each spring seating against the closed edge of the member 5. The springs I tension the male member 4 against the sash 2, as will be clear, so that the sash is tensioned against the usual guide strip, not shown, and thereby prevented from rattling. The tensioned male member 4 cooperates with the sash Z to form an air tight connection therebetween and thereby functions as a weather strip.

The guide groove 9 and screws 9' cooperate to lock the strip 3 against swinging movement .on the hinges I. By prying the male member 4 inwardly of the female member 5, as with a screwdriver, until the screws 9 are disengaged from the groove 9, said strip 3 may be swung on said hinges "I out of the frame I.

. The details of construction, operation, and advantages of our invention will, it is believed, be apparent from the foregoing description thereof.

Manifestly modifications of details described in the foregoing may be resorted to without departing from the inventive concept and right is herein reserved to all said modifications, falling within .the scope of the claim appended hereto.

What we claim is:-

The combination with a window frame having a sash therein, of a window strip comprising strip-like male and female members, respectively, the latter hingedly attached to the front corner of the frame to normally lie flat against the latter and to swing outwardly thereof and correspondingly swing the male member, said male member telescoping edgewise' in the female membeer for movement into and out of the same and being tensioned against movement in the former direction whereby in the normal position of said female member said male member yieldingly bears at one edge against the sash, said edge of the male member being longitudinally grooved and the sash having vertically spaced studs extending therefrom and fitting into said groove, whereby the strip is interlocked with the sash against lateral swinging movement and adapted to be freed for such movement by telescoping of the male member inwardly of the female member.
